UGMIC Technical Advantages & Core Synergistic Effect Advantages

UGMIC integrates and matches various technical functions such as thread clearance(back-relief), straight flutes, spiral flutes, tip flutes, extrusion function, center internal cooling, thread interrupted structure, and specially selected tungsten steel according to different thread processing requirements.

The core concept of UGMIC is not simply to add a single function, but to create a synergistic effect between different functions in terms of cutting, chip removal, cooling, lubrication, friction reduction, torque reduction, tool sticking prevention, chip jamming prevention, thread damage reduction, and maintaining thread dimensional accuracy.

UGMIC's core technological advantages:

Core advantages of selecting thread cutting tool materials:

• Special tungsten steel threaded cutting edge: high rigidity + high hardness + wear resistance + extremely high red hardness

➢ High rigidity: Strong resistance to cutting deformation, ensuring consistent thread accuracy during machining.

➢ High hardness: Compatible with difficult-to-machine materials such as high-hardness tempered steel and quenched steel.

➢ Wear resistance: Extends threading tool life, reducing costs and time wasted due to frequent tool changes.

➢ Extremely high red hardness: It can maintain excellent hardness, strength and cutting ability even under high temperature and high speed cutting environment.

• High-speed steel HSS-Co (SKH55, M35) thread cutting edge: high toughness + high chip breaking ability + wear resistance + high temperature red hardness

➢High toughness: High torque is generated during thread cutting. High toughness allows thread cutting tools to withstand high torque, and the thread edge is less prone to chipping or breakage.

➢ High chip breaking capability: During thread cutting, chips easily stick and get stuck at the bottom of the threaded hole. A good chip breaking design allows chips to be cut off and discharged smoothly, preventing chips from sticking, tangling, or scratching the thread surface.

➢ High wear resistance: The cobalt-containing high-speed steel HSS-Co (SKH55, M35) with a relatively high tungsten-cobalt ratio maintains excellent toughness while possessing excellent high-temperature hardness. Thread cutting tools remain sharp even under prolonged friction, significantly extending their service life.

➢ High temperature red hardness: High temperature red hardness means that thread cutting tools can maintain their hardness under the high heat generated during cutting,and are not prone to softening and failure due to overheating.

Technical advantages:

• Thread Back Relief：Due to the high-temperature adhesion, high-temperature annealing, and high temperature caused by continuous friction across the entire surface during machining, thread clearance(back-relief), combined with precise dimensional control, allows for "perfect clearance(back-relief)" when the tap reverses and retracts. This not only reduces the torque and frictional resistance during the cutting process but also reduces secondary friction with the already formed thread surface, ensuring thread dimensional accuracy and the inspection of thread gauges and plug gauges.

• Straight Flute：Designed specifically for short-chip materials and high-hardness hand-operated threads, the straight flute thread has a high-strength cutting edge structure that can withstand higher cutting torque. The cutting edge characteristics of the straight flute tap are more suitable for achieving chip breaking, avoiding chip clogging, chip jamming, and chip sticking problems. It is most commonly used in mechanical rigid taps for non-ferrous metals such as copper, aluminum, cast iron, and zinc, as well as hand-operated tungsten steel taps for high-hardness materials, and easily meets the cutting edge requirements of long threads.

• Spiral Flute：Designed specifically for mechanically rigid tapping of blind hole threads, it forcibly pulls the chips out of the hole, preventing chips from accumulating at the bottom of the hole and reducing the risk of chip jamming, chip sticking, and chip adhesion.

• Pointed Flute：Designed specifically for mechanically rigid tapping through threads, it forcibly pushes chips forward out of the hole, preventing chips from accumulating at the bottom of the hole and reducing the risk of chip jamming, chip sticking, and chip adhesion.

• Roll forming：Designed specifically for mechanically rigid tapping of ductile materials, it uses a roll forming method to extrude material of a suitable lower diameter size to form a complete thread. The process produces almost no chips, but special emphasis is placed on lubrication and cooling functions to ensure stable thread size and thread tool life, and to eliminate the risks of chip jamming, chip sticking, and chip adhesion.

• Internal-Coolant：Through the central water outlet function of the spindle, the cutting fluid is sprayed directly from the bottom of the threaded hole through the threaded tool holder with the central internal-cooling hole. The high-pressure cutting oil, together with the chip removal flutes, forms a powerful "back thrust", which washes the chips out along the chip removal flutes (oil flutes) like cleaning the flutes. At the same time, it meets the high-efficiency requirements of enhanced cooling, enhanced lubrication and enhanced chip removal in the hole and the stability of thread product quality.

• Thread Interrupted structure：Thread Interrupted Structure: The cutting area of the tapered thread is halved, and the torque drops by more than 40%. This increases the chip removal space, prevents secondary friction damage between the chips and the thread surface, prevents high-heat sticking of lead-free copper or high-toughness and high-resilience materials, reduces friction area, reduces high-heat generation, reduces sticking, reduces chip jamming, and improves efficiency by 25~45%.

UGMIC Multifunctional thread tools technology integration - core synergistic effect advantages:

UGMIC has long observed that the advantages of a single function in threading tools are extremely limited. Therefore, it continuously strives to maximize the optimization effect of the various functions available to threading tools, achieving a synergistic effect where 1+1>2.

UGMIC's multi-functional advantages :

Thread back-relief perfectly complements specially selected tungsten carbide：

➢The thread back-relief has excellent anti-spring-back capability, and the specially selected tungsten steel has extremely high bending strength and hardness (ultimate rigidity). When faced with the "spring-back compression force" of lead-free copper or high-toughness materials, the specially selected tungsten steel, combined with the complete cutting performance of the thread clearance(back-relief), meets the requirements of the thread specifications (effective diameter P.D. + maximum diameter Major Dia. + minimum diameter Minor Dia.) for high-precision tungsten steel taps, achieving perfect tooth profile and thread accuracy.

The thread interrupted structure works perfectly with the central internal cooling system：

➢The contact area is halved (40-50%), the chip removal space is increased (40-50%), the cutting torque of tapered threads drops by more than 40%, and the spring-back and high-heat sticking of lead-free copper or high-toughness materials are prevented. The friction area is reduced, the high heat generation is reduced, the sticking of the tool is reduced, the chip jamming is reduced, and the efficiency is increased by 25-45%.

➢Because the chipping from the reverse retraction of the tap during machining can easily engage the workpiece, the ample space of the thread interrupted structure allows for "perfect clearance(back-relief)" of the thread when the tap reverses and retracts, reducing secondary friction between the chips generated during retraction and the already formed thread surface, ensuring the thread dimensional accuracy meets the requirements of thread gauges and plug gauges.

➢With the chip removal function of the thread interrupted structure, the high toughness material resisting spring-back, and the prevention of chip trapping, jamming, and damage to the thread, the addition of the central internal cooling function to force cooling, forced lubrication, and forced flushing of chips to the outside can be said to maximize the functions and benefits of the thread tap (thread cutting die).

Multiplied optimization effect=thread back-relief + specially selected tungsten steel + thread tool structer + internal cooling + thread interrupted

Spiral flutes + thread back-relief (dedicated parameter #C) + thread interrupted structure + internal coolant perfectly matched:

➢The spiral flutes guide the chips backward, the thread interrupted structure increases the chip removal space and radial path, and the central internal cooler handles high-pressure outward pushing, simultaneously meeting the high-efficiency requirements of enhanced cooling, lubrication, and chip removal within the threaded hole, as well as ensuring the stability of thread product quality. Combined with the high wear resistance of specially selected tungsten steel and the high cutting characteristics of the thread clearance(back-relief), even at increased cutting speeds (25~40%), the thread clearance(back-relief) is not easily worn down rapidly due to chip friction, resulting in a lifespan several to tens of times longer than that of ordinary high-speed steel.

Straight flutes + thread back-relief (dedicated parameter #A) + thread interrupted structure +internal coolant perfectly matched:

➢The straight flutes thread cutting edge provides chip breaking and chip removal space, while the interrupted threads structure increase chip removal space and radial path. The central internal cooler handles high-pressure outward pushing, simultaneously meeting the high-efficiency requirements of enhanced cooling, lubrication, and chip removal within the threaded hole, as well as ensuring the stability of thread product quality. Combined with the high wear resistance of specially selected tungsten steel and the high cutting characteristics of the thread clearance(back-relief), even at increased cutting speeds (20-40%), the thread clearance(back-relief) is not easily worn down rapidly due to chip friction, resulting in a lifespan several to tens of times longer than that of ordinary high-speed steel.

Roll Forming + Thread Back-Relief (Dedicated Parameter #RH) + Internal Coolant = Perfect Combination

➢Roll Forming: Designed specifically for mechanically rigid tapping of ductile materials, the forming tap uses a roll forming method to extrude suitable material from the lower hole diameter and form a complete thread. The process produces almost no chips, significantly reducing the risks associated with conventional cutting taps, including chip jamming, chip sticking, and chip adhesion. However, because roll forming relies on high-load plastic deformation of the material, lubrication and cooling are particularly important. The dedicated Thread Back-Relief parameter #RH, combined with internal coolant, helps reduce unnecessary friction and heat accumulation during the forming process.
The high-pressure cutting fluid provides:

Forced Cooling + Forced Lubrication + Stable Forming

thereby supporting stable thread dimensions, thread accuracy, and thread tool life.

UGMIC Core Synergistic Effect

UGMIC possesses a precise technological core, which does not exist in isolation for various functions, but rather matches and integrates different functions according to machining principles and working conditions.

Its core logic can be expressed as:

"Single Function" → "Function Combination" → "Mutual Reinforcement" → "Multiple Improvements"

Ultimately resulting in:

UGMIC Multifunctional Threading Tool = Cutting + Clearance(back-relief) + Chip Removal + Cooling + Lubrication + Anti-Spring-back + Reduced Friction + Reduced Torque + Stable Thread Quality

UGMIC Technology Integration Core

UGMIC integrates technologies such as thread back-relief, straight flute, spiral flute, pointed flute, roll forming, internal cooling, thread interrupted structure, and specially selected tungsten carbide to establish a multi-functional thread tool technology system.

Its core is not simply pursuing a single performance characteristic, but rather selecting a suitable structural combination based on different workpiece materials, thread types, blind holes/through holes, mechanical rigidity tapping, machining load, chip removal requirements, lubrication requirements, and thread quality requirements.

Therefore, UGMIC's multi-functional thread tool technology can:

Thread backlash → Reduce friction    
Selected tungsten steel → Improve wear resistance and extreme rigidity
Straight grooves/helical grooves/tip grooves → Establish corresponding chip control directions
Thread skip structure → Increase chip removal space, reduce contact area and torque
Center cooling → Forced cooling + forced lubrication + forced chip flushing
Extrusion function → Form a complete thread through roll forming
Forming a complete multi-functional collaborative machining system.
